[Cystic meningioma. 3 cases].

The association of a meningioma and an arachnoid cyst is one of the many association of cyst and meningioma. The diagnosis could be difficult by CT scan. We report three cases of parameningiomal cysts and discuss their different mechanism of formation before stressing practical problems.

[Diagnostic and prognostic value of diaphragmatic electromyography and somatosensory evoked potentials in cervical spine and spinal cord injuries].

SEP contribution to diagnosis is interesting but limited to hardly examined complete syndromes in an emergency care unit. The predictive value of SEP is high if electrophysiological data are correlated the 10th. day with the clinical status. A good prognostic value is shown when the clinical posterior column and pyramidal tract dysfunctions are equal in intensity and distribution, i.e. in complete syndromes or central spinal cord syndromes or Brown-Sequard's ones. However, not any correlation exists in cases of anterior spinal cord syndromes. Dg.EMG. is an easy, atraumatic useful tool for the clinician. It must be a systematic approach of the brain stem and cervical spinal cord phrenic centers vitality that may be involved by the trauma. When a respiratory deficiency occurs, it allows the diagnosis of a "peripheral" or "neurological" etiology. Its high prognostic value for m tor diaphragmatic function (increase or decrease) must be discussed before any therapeutic decision.

[Clinical and prognostic evaluation of post-traumatic coma according to the level of brain stem injury].

On the grounds of studies carried out in the last ten years, the authors criticize the usual classification of comas and question the Glasgow scale (opening of eyes, verbal answer, motor response). Their description of brain stem injury by axial herniation and explanation of the role of diffuse encephalic lesions causing intracranial hypertension is based upon anatomo-clinical findings and results of investigations in comatose patients with head injury. For prognostic purposes, a simple and fairly reliable classification of post-traumatic comas is proposed. Comas are divided into five stages of rostro-caudal destructuration (cortico-sub-cortical, diencephalic, meso-diencephalic, mesencephalic and pontic) by studying the response to pain (unadapted, adapted, absent) and four brain stem reflexes (fronto-orbicular, vertical and horizontal oculocephalic, light reflexes).

[Post-traumatic cerebral edema. Physiopathology and treatment].

Severe head injury often produces complex intracranial displacements of the brain, resulting in widespread, often microscopic lesions. These are responsible for two types of edema: vasogenic edema, with outflow of molecules and fluid into the extracellular spaces by rupture of the blood-brain barrier and vasoplegia, and cytotoxic edema, with swelling of astrocytes due to membrane lesions. The connexions between these two types of edema are still obscure. Alterations in membrane phospholipids may impede function of Na-K pump enzymes, causing accumulation of water in the cell. Cerebral edema is responsible for intracranial hypertension and tentorial herniation, which in turn increase edema through venous compression, ischemia, and hypoxia. The least controversial anti-edema therapeutic measures include relative fluid and salt restriction, mannitol if called for, neuroplegia, in particular with diazepam and Gamma-OH, and assisted ventilation.

The anterior approach and plates in lower cervical posttraumatic lesions.

Between 1949 and 1982, 290 patients were operated on for lesions of the lower cervical spine. Since 1970 the combined use of the anterior approach and more and more sophisticated osteosynthesis equipment has led us to revise our therapeutic policy with regard to 160 patients. The results, advantages, and disadvantages of this policy are discussed hereafter.

Prognosis with 500 ruptured and operated intracranial arterial aneurysms.

Based on a series of 500 operated intracranial aneurysms in 486 patients, we have analyzed the results of current neurosurgical treatment. The overall results (75% cures, 13% poor results, 12% deaths) depend on several factors, which have all to be analyzed: the age and general condition of the patient; the topography and mode of rupture of the aneurysm; and the timing of the surgical intervention.

[Fractures of the sacrum with neurologic complications. A case].

The fractures of sacrum are rare and the literature is poor on their etiopathological aspects and possible complications. According to a sacral transverse fracture with neurological complications by epidural hematoma we analyze the different mechanisms to obtain this one.
